ABSTRACT
Vapor pressures and molar enthalpies of vaporization of the 2-amino-ethanol, 2-(methylamino)-ethanol, 2-(ethylamino)-ethanol, 2-(dimethylamino)-ethanol, and 2-(diethylamino)-ethanol have been determined using the transpiration method. The strength of intra-molecular hydrogen bonding in ethanolamines have been derived and discussed in terms of the difference between the enthalpy of vaporization of an alkanolamine and an appropriate homomorph (alkylamine).
